JEAN SULLIGER, OF GENEVA., SWITZERLAND.

MOWING-MACHINE.

To all whom it may concern:-

Be it known thatI I, JEAN SULLicsii, a citizen of the Republic of Switzerland, and residing at Geneva, Switzerland, have invented new and useful Improvements in Mowing-Machines, of which thc following is a specification.

This invention relates to certain new and useful improvements in mowing machines.

The invention has for its object the production of a machine of this character in which both of the cutter 'bars are recipro cated.

A further object is to provide improved means for operating said cutter bars. W'ith these ends in view the invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a plan view of a mowing machine constructed in accordance with my invention. Fig. 2 is a side view thereof` Fig. 3 is a de tail sectional view illustrating the cutters. Figs. 4 and 5 are details of the actuating mechanism for the reciprocating cutter bar. Fig. 6 is a detail of the clutch controlling the operation of the cutter bars. Fig. 7 is a side view partly in section, and Fig. 8 is a plan view of a modified form of knife driving apparatus. Fig. 9 is a detail sectional view thereof. Fig. 10 is a detail sectional view on line :v -a.' Fig. 2.

Referrin to the drawings, 1 designates a power sha t driven by a motor 32 and provided with a Worm meshing with gear 2 carried by the axle 3 ofa suitable supporting frame. Said drive shaft is provided with a pinion 4, meshing with a gear 5 driving a crank 6 which is connected by link 7 with the crank 8 of a shaft 9, rotatably mounted in a support 10. Said support is prolonged to form the horizontal support 11 which is provided with the lateral arms `12, the free ends of which are supported by the shoes 13. These arms 12 also support theV finger bar 15 upon which the cutter bars 16 and 17 are mounted to reciprocate.

d are secured. (See Fig. 3.) The blades are hollow and provided with strengthening ribs b and two ranges of grooves to receive antifriction balls a, said blades bein held in operative relation by means of over anging guides f carried by a rib e formed with the lower blader The shaft 9 is provided with a crank 18 Specification of Letters Patent.

, provided with the arm l engaging a slide m mounted to reciprocate in guides n formed with the upper cutter bar, whereby said upper bar is reciprocaled. One end of said bar is provided with a slide connected with a lever 19 pivoted-to a pin 23 carried by one of the shoes 13,said slide being mounted in guides 20, the'otlier end of said lcverbeing" connected to a slide mounted between guides 21 of a projection 22 of the lowerknife. In

this manner the lower'cutter is reciprocated simultaneously with the reciprocation of the upper cutter but in the opposile-dii'ection.`

In order to stiften the 'shoe lagainst the strains incident to this arrangement'a's'uitable brace 24 is provided. 1

The connections with the motor are controlled by a suitable clutch operated by'lei ver 27 connected b v means of a cable 26 with a hand lever A hand lever 28 is connected to one end of a cable 2f) the other end of the Iatterbeing connected to a bell crank connected to a rock shaft 30. Said rock shaft is connected by means of a second bell crank with a rod 3l. Said rod is provided with a finger c which engages the ring R of movable clutch member la, slidably mounted in a groove 5'/ of the axle 3 which latter is provided with a comple mental clutch portion ujthin the hub of wheel lV and adapted to be moved by niov able member 71. By this arrangement the wheel lV may be driven from motor 32 or not, as may be desired.

In Figs. 7, 8, and 9 I have illustrated a modified vmechanism for the driving of the knives. In this form the cranks of the crank axle y' which is driven by the motor axle r, are'surrounded by the pieces y connected by arms o with the knives o. The tube g within which the axle r is mounted, is made integral with the frame of the carriage, and

bears the support Il: by means of rings k'; on both sides of this support are bolted the lateral arms 7i and p provided all along with chines comprising upper and lower'cuttcr bars, guide fingers for one of said bars carried by the other bar, a slide carried by one of said bars, means engaging said slide for reciprocating said bar, and means operated by said bar for reciprocating the other bar.

2. Cutting mechanism for mowing machines comprising upper and lower cutter bars, supporting shoes therefor guide fingers for one of said bars carried by the other bar, a slide carried by one of said bars, a drive shaft provided with a crank engaging said slide to reciprocate said bar, a lever supported by one of said shoes adjacent one end of the last mentioned bar and connected with the latter, and connections between said lever and the end of the other bar.

3. Cutting mechanism for mowing machines comprising upper and lower cutter bars, supporting shoes therefor guide fingers for one of said bars carried by the other bar, means for reciprocating one of said bars, a lever pivotally supported by one of said slices, and slides carried b each bar' and operatively connected with t e opposite ends of said lever. I

4. Cutting mechanism formowing machines comprising `upper and lower cutter bars, guide fingers for oneof said bars car ried bythe other bar, guide bars caiii'e byrone of said cutter bars, a. slide mounte between said guide bars, a crank shaft connected to said slide, and means operated by said cutter bar for actuating the other cutter bar.

5. Cutting mechanism for mowing machines comprising upper and lower cutter bars, guide fingers for one of said bars car ried by the other bar, guide bars carried by one of said cutter bars, a slide mounted between said uide bars, a'crank Shaft connected to said slide, a projection carried by the other cutter bal.` and rovided with guide arms, a slide mounte between said guide arms, and a lever engaging said slide and operatively connected with the other bar.

6. Cutting mechanism for mowing machines comprising u per and lower cutter bars, the lower bar eing provided with a longitudinal rib, guide fingers for the upper bar secured to saidrib, means for reciprocating the upper bar, and means operated by the upper bar for reciprocating the lower bar.
